Abstract: This paper investigates the use of both simple and complex models in estimating annual nonpoint urban pollutant loads. Using four case studies, 124 comparisons are made between pollutant load estimates determined by a simple model, based on the product of average pollutant concentration and annual runoff, and those determined using more complex, multiparameter hydrologic modeling methods. Estimates made with these two methods are all within an order of magnitude of each other; 112 are within a factor of three; almost three‐fourths are within a factor of two or less. Because of the uncertainty in storm runoff concentrations, there is little quantitative reason for using complex models when estimating annual non‐point‐source pollutant loads for urban areas.
